Vacuum feed ngokusebenzisa i-alumina Metallized Ceramic

  Ngaphansi kwezimo ezijwayelekile, i-alumina ceramics inokumelana nokushisa okuphezulu, ukumelana nokugqoka, ukumelana nokugqwala, amandla aphezulu, ubulukhuni obuphezulu, ukufakwa kahle kwe-insulation nezinye izici, kodwa ukusebenza kwayo kokucubungula, ukusebenza kwe-welding kubi. Kodwa-ke, izinto zensimbi zinezinzuzo zokumelana nokushisa okuphezulu, ukumelana nokugqwala, amandla aphezulu, ukuhanjiswa kahle kukagesi, nokusebenza okuhle kwemishini nokusebenza kwe-welding. Ngokunwetshwa okuqhubekayo kwensimu yesicelo se-ceramics yesakhiwo esisebenza kahle kanye nokuthuthukiswa kwezidingo zobuchwepheshe obuphezulu, izingxenye eziningi zivame ukudinga izakhiwo eziphelele zezinto ze-ceramic nezensimbi. I-Ceramic nensimbi ingahlanganiswa ngokwemvelo ngenqubo ye-ceramic metallized vacuum brazing, futhi izingxenye zesakhiwo eziyinhlanganisela ezinobuhle bazo zombili i-ceramic nensimbi zingatholakala.

Ngenxa yokuthi ukwakheka kwezinto ze-ceramic kuhlukile ku-microstructure yezinto zensimbi, i-filler metal ngokuvamile ayikwazi ukumanzisa indawo ye-ceramic, futhi ayikwazi ukusebenza kuyo ukuze yakhe isibopho esiqinile, ngakho-ke ukubekwa uphawu kwe-ceramics nezinsimbi kuyindlela ekhethekile yenqubo, okungukuthi, indlela ye-ceramic metallization: okokuqala unamathele ngokuqinile kungqimba lwefilimu yensimbi ebusweni be-ceramic edinga ukukhanda, ukuze ubuso bube nezici zensimbi. Bese uqaphela ukugqama kwe-ceramic nensimbi. Ngemva kokwethulwa kolwazi olufanele, indlela ekhona ye-molybdenum kanye ne-manganese, indlela yokufakwa kwegolide, indlela yokuhlanganisa ithusi, indlela yokuhlanganisa ithini, indlela yokufaka i-nickel, indlela ye-LAP (i-laser metal plating) nezinye izinqubo ze-ceramic metallization.

I-vacuum brazing alumina metallized ceramic iyinqubo lapho i-solder enephuzu elincibilikayo elingaphansi kwesisekelo sensimbi incibilika futhi igebe elihlangene ligcwaliswa isenzo se-capillary ukuze kutholwe ilunga elingakhipheki. Inqubo ye-vacuum brazing inezinzuzo zokungabi nasidingo sokusebenzisa i-flux aid kanye nokuqina okuhle kwe-brazing spot ngenxa ye-deoxidation. Eminyakeni yamuva, ngokuthuthukiswa okuqhubekayo kwesayensi nobuchwepheshe, ubuchwepheshe be-brazing buthatha isikhundla esibalulekile emikhakheni ehlukahlukene yezimboni, ikakhulukazi ku-instrumentation kagesi kanye nokuvikela kazwelonke kanye nezinye izimboni isiphenduke indlela yenqubo engenakuthathelwa indawo. Isibonelo, amajeneretha amakhulu e-oxygen, ama-heaters anezimo eziyinkimbinkimbi (ama-coolers kawoyela, ama-evaporator nama-radiator, njll.) asetshenziswa ezimotweni nasemikhumbini, izakhiwo zekhekheba lezinyosi ezinobunjwa obuyinkimbinkimbi ezinjinini ze-jet, izingxenye zikagesi, izingxenye zemishini ezinembayo, njll., kufanele brazed.

Kuleli phepha, uchungechunge lokuhlolwa kwezobuchwepheshe kanye nezicelo zokukhiqiza ze-vacuum brazing zenziwe. Isihluthulelo se-brazing yigebe elifanelekile lokuhlangana, ukukhetha okulungile kwemingcele yenqubo yokubhoboza kanye nenqubo ye-vacuum brazing.
